I just returned from a BW trip last week and the lower zipper on my eureka tent has a sticky spot. Maybe I bent the teeth doing the bad thing of opening by pulling on the door flap, but the teeth look good. Its only in one spot about 16" from the end and the teeth are plastic coated.
So is my zipper due for replacement or is there a lubricant you can put on the coated teeth that won't eat the zipper or adjacent cloth?
You could try putting graphite lubricant on the zips. That might help.

LOL, that's a good idea to let someone else use it and distract the critters from your own tent!
I usually use a tea candle as it's just the right size, it's unscented, and the wife usually has some laying around here and there. Used it on tents, wetsuits, and rain gear zippers. Three or four swipes across each side of the zipper and it seems to work smoothly and quietly afterward.

Agree on the Mc Netts. I do not use WD 40. That has an unfortunate attribute of attracting more dirt to mess up the zipper. While I have not used it on zippers I have found that out from lubricating kayak paddle ferrules.
what I've done since a youngster in scouts is use a bar of soap. It doesn't damage the material like oils can and its generally available when out camping. It's also works great on leathers and doesn't attract dirt.
McNett zip care has saved many zippers from replacement. Folks have brought items with zippers they thought were toast. Working in the Zip care made the zippers function as they should.

Suitable method of cleaning A zipper should be closed and the slider fixed before cleaning. Left open, the tip of the slider may damage the fabric or the tape may become stretched or may shrink.Strong alkaline detergents or chlorine bleaching agents used to remove oil or stains dissolve paraffin or oily film and must be used with care.If a zipper does not work smoothly after cleaning, apply paraffin or the lubricating spray "ZIPPYCOOL®," and work the slider up and down several times until it works smoothly.

Goes on as a liquid and then coats and dries. It has a brush aplicator built into it so you can get all of the teeth. Most Zipper Failures as a result of use is from wearing out the zipper pull. Once the pull is replaced the zipper has another life. The lubricant / dirt repellent is to prolong the wear that dirt has on the pull. I have never seen the teeth of the zipper to wear before the pull. Get the nickle plated zipper pulls, they always last longer than the painted ones.
